With continued reference to fig. 2, the visual element 5 (e.g., glass tube), the sealing elements 6, 7 and the wheel element 15 of the flow indicator are assembled between the flange surfaces 1, 2 of the cooling water outlet conduit and then secured to the outlet conduit 24 by the bolts 3 and nuts 4. The two flange surfaces 1, 2 of the pipe flange are fixed by nuts 3 and bolts 4, so that the visual element 5 and the wheel element 15 are fixed between the two flange surfaces 1, 2.
Referring to fig. 3, the rotating wheel 8 and the mandrel 12 are connected and installed through a bushing 10, and the rotating wheel 8 is movably fixed on the mandrel 12 through a screw 13. A gasket 14 is arranged between the shaft sleeve 10 and the mandrel 12, the shaft sleeve 10 and the mandrel 12 are in clearance fit, and a clearance delta is reserved between the gasket 14 and the end face of the shaft sleeve 10.
In a preferred embodiment of the invention, the holder 11 is circular and has a diameter greater than the outer diameter of the pipe and smaller than the inner diameter of the visual element 5. The outer periphery of the bracket 11 is flanged to cooperate with the sealing member 7 for sealing. Furthermore, the wheel 8 is circular and has a diameter smaller than the diameter of the support 11. It will be appreciated by those skilled in the art that the support 11 and the wheel 8 may be of other shapes than circular, preferably circular, primarily to better fit the shape of the pipe. In other embodiments, the support 11 and the rotating wheel 8 may have other shapes, which are consistent with the technical solution of the present invention.
As an optimal implementation mode of the visual component 5, the visual component 5 adopts a glass tube, preferably tubular toughened glass, so that the water flow condition in the pipeline can be checked from the periphery, the observation is convenient, certain pressure and temperature can be borne, and the safety is good. It should be understood by those skilled in the art that the use of a glass tube or tempered glass as the viewing component 5 is only one of many embodiments in the art, and in other embodiments, the viewing component 5 may be made of other transparent materials, and still fall within the scope of the present invention.

Fig. 4 shows a cross-section of section a-a of fig. 2, and it can be seen from fig. 4 that the runner 8 comprises a plurality of blades 16, so that the water flow through the blades 16 forces the runner 8 to rotate. When designing the blades 16 of the runner 8, the rotating speed V of the runner 8 is within a certain range (within a range convenient for observation) by adjusting different blade shape parameters or by using CFD software simulation analysis within a permissible flow range.
Further, as shown in fig. 3, an outer hub is provided at the outer circumference of the blade 16, and a direction arrow 9 is provided on the outer surface of the outer hub. Preferably, an outer hub is arranged at the outer circle of the blade 16 of the runner 8, so that the strength of the blade 16 can be improved, and meanwhile, the direction arrow 9 can be made on the outer surface of the outer hub, and the direction arrow 9 is coated with red, so that the rotation condition of the runner 8 can be observed conveniently. With continued reference to fig. 4, the carrier 11 comprises a plurality of (radial) ribs 17, which ribs 17 radiate outwards in the radial direction of the carrier and are therefore also referred to as radial ribs.

It will be understood by those skilled in the art that the number of webs 17 and blades 16 is merely illustrative and not a limitation of the present invention. In other embodiments of the present invention, the number and shape of the rib plates 17 and the blades 16 can be determined according to the diameter, the flow area and the actual flow rate of the pipeline, which all meet the gist of the present invention.
As a preferred embodiment of the invention, the rotating wheel 8 and the bracket 11 are made of high-strength engineering plastics, have good erosion resistance and no corrosion, and can be manufactured by a die pressing process. The mandrel 12 and the shaft sleeve 10 are made of copper or stainless steel materials, so that the wear resistance is good, and the service life of the flow indicator can be prolonged. When in mould pressing, the processed core shaft 12 is directly moulded in the bracket 11, and the processed shaft sleeve 10 is directly moulded in the rotating wheel 8, so that the processing and manufacturing cost can be reduced.
It should be understood by those skilled in the art that the selection of the materials for the rotating wheel 8, the bracket 11, the core shaft 12 and the sleeve 10 is only one of the embodiments of the present invention, and the rotating wheel 8, the bracket 11, the core shaft 12 and the sleeve 10 of the present invention may be made of other materials to achieve the technical solution of the present invention.
When the flow indicating system and the flow indicator of the invention are in working states, when water flows through a drainage pipeline, the water flow pushes the rotating wheel 8 and the shaft sleeve 10 to rotate on the mandrel 12 together, so that the flowing state of the water flow in the drainage pipeline can be conveniently observed from the periphery of the visual component 5, and the flow rate of the water flow can be generally judged according to the rotating speed of the rotating wheel 8.
